Geons, Black Holes, and Quantum Foam: A Life in Physics.Geons, Black Holes, and Quantum Foam Quantum foam, also referred to as spacetime foam, is a concept in quantum mechanics, devised by John Wheeler in 1955. The foam is a qualitative description of the turbulence that the phenomenon creates at extremely small distances of the order of the Planck length. : A Life in Physics (W.W. Norton, 2000) by John Archibald Wheeler John Archibald Wheeler (born July 9, 1911) is an eminent American theoretical physicist. One of the later collaborators of Albert Einstein, he tried to achieve Einstein's vision of a unified field theory. . Here's the book that answers the questions: "What do we know about time and how did we come to know it?" Bigger, though not as dense as Stephen Hawking's A Brief History of Time, this autobiography by one of the most important American physicists of the 20th century offers a bird's-eye view bird's-eye view Noun 1. a view seen from above 2. a general or overall impression of something bird's-eye view n → vista de pájaro of most of the folks (Albert Einstein, Enrico Fermi Noun 1. Enrico Fermi - Italian nuclear physicist (in the United States after 1939) who worked on artificial radioactivity caused by neutron bombardment and who headed the group that in 1942 produced the first controlled nuclear reaction (1901-1954) Fermi , Niels Bohr, J. Robert Oppenheimer, and Richard Feynman) who developed the theories and discovered the secrets of space and time. It is also a fascinating tale of the passions that fuel our quest for knowledge--and the adventure of learning. |
